APPARATUS FOR MAKING SULPHURIC ACID.

SPECIFICATION forming part of Letters Patent No. 349,241, dated September 14, 1886.

Application filed October 13, 1884. Serial No. 145,371. (No model.) Patented in Austriall'nugary April 7, 1884, No. 2,034; in Belgium June .19, 1884, No. 65,531; in England June 23, 1884, No. 9,317; in Germany June 26, 1884, No. 30,211; in France October 8, 1894, No. 162,828, and in Spain April 25, 1885, No. 4,707.

To all whom it nmy concern:

Be it known that I, JEAN JACQUES Tnvss, manufacturer of'che nicals, a citizen of the Republic of France, and residing in Bakon, Cain casus, Russia, have invented Improvements in Apparatus for the Production of Sulphuric Acid, of which the following is a specification.

The apparatus which forms the subject of the present application for a patent is intend-' Figure 1 of the accompanying drawings is a vertical section of the apparatus, and Fig. 2 is a plan.

In the base of the column of lead are fitted fifteen posts of wood lined or covered with lead. These posts are firmly fixed at the bottom,so as to secure them from movin A frame of lead twenty-two millimeters in thick ness and fortyeight millimeters in height is placed in position. On this frame is placed a sheet of lead of the width and length of the frame. This sheet is two millimeters in thickness, and is perforated with seventeen hundred and fifty holes of one centimeter in diameter, with one centimeter of metal left between each hole. The second frame is made to rest on the first by placing three small supports of wood lined or covered with lead of equal distances apart between or among the plates, in order to sustain the weight of the sheet of perforated lead. This successive overlaying is continued until there are twenty-four frames and twenty-four sheets of lead. The sulphuricacid gases and steam pass through the holes of the plate and impinge on the parts not perforated, whereby they are forced to seek other outlets; and it is by this multiplied contact that the oxidation is effected, and that the sulphurous acid is converted into sulphuric acid by introducing, it is to be observed, a

jet of steam into each column. The gases, L

with the steam, pass from top to bottom through the perforated plates, drawing the small drops of sulphuric acid which are collected at the bottom of the column. The column is put in communication with the last compartment of the chamber by means of a leaden pipe, offifty centimeters square in section, into which is introduced a jet of steam, in order to quicken the formation of the sulphuric acid and protect the lead from azotic acid. The gases and steam enter by an opening at the bottom part of the column (without frames) and pass into a second column furnished with twenty-fourframes and perforated plates. In this column the uncondensed gases meet a jet of steam. The distribution is thus continued onward to the last column. The uncondensable gases are conducted in a leaden pipe of thirty-five centimeters in diameter, in which a strong draft is produced by a jet of steam, in order to draw the gases into the air and produce the required draft in the sulphur-furnace. Each column furnishes in twenty-four hours seven hundred and thirtysix kilograms of sulphuric acid, reckoned at sixty-six Beaum, (specific gravity 1.842.) The number of columns can be in creased at will, according to the scale of operations in the manufactiu'e of sulphuric acid.

The accompanying drawings give a correct View of the system. A is the pipe, of lead, or channel, which conducts from the drum or compartment of lead the sulphurous gases and vapors into the column. B is the steanrpipe, furnished with cocks. .O is the column, of lead, and D the supports, of wood lined or covered with lead, the frames of lead and sheets of lead being perforated with holes. E represents twenty-four frames of lead with twenty-four sheets of perforated lead placed one on the other. e e e are the supports, of wood lined or covered with lead, which support the sheets of perforated lead. F is the aperture through which pass the sulphurous gases into the empty column, and G is the aperture through which pass the uncoudensed gases into a column, in which are placed the same number of frames as in the first column, and so on in succession even to the leaden pipe H, which conducts the ineomlensahle gases out of the building. In thispipethereisa steanrpipe for regulating the draft of the I'm-nave for generating snlphnrons avid, as well as the renewing of atmospheric air in the ehamlwrs amt golnmns. The gases and vapors are eondut-twl from, top to bottom throughtheperloratet'l plates of the columns, in order to i'aeilitate tluillowing ofthe sulphur in acid as it is formed.

I claim as my invention- 1. The herein-(leserihe 1 eontlenser t'or S111- phnrieaeid gas, said eondenser consisting of a series ot'atljoining vertieal leaden fines eommnnieating' with each other at the top and bottom alternately and eaeh alternate fine ("outaining a column of perforated leaden ShtOt'S Separated from each other. snhstantially 11S Set forth.
